Polar-direct-drive implosions at the National Ignition Facility generated large plasma volumes to study the 3He + 3He fusion reaction. The dataset, authored by a team from the Plasma Science and Fusion Center, contains results showing 30% of the D3He-proton spectral width was due to stopping power, with residual flows contributing 10%. The 3He temperature was determined as 12.4 ± 3.2 keV, corresponding to a Gamow energy of 95 ± 14 keV.
Use Cases
- Calibrating fusion reaction models based on measured ion temperature and Gamow energy.
- Analyzing plasma stopping power effects on proton spectral broadening.
- Benchmarking simulations of high energy density plasmas against experimental results from the National Ignition Facility.
- Studying conditions relevant to solar fusion processes based on the achieved Gamow energy.
Strengths
- Results are derived from experiments at the National Ignition Facility, a leading high-energy-density facility.
- Specific quantitative results are reported, including a 3He temperature of 12.4 ± 3.2 keV and a Gamow energy of 95 ± 14 keV.
- The experiments achieved the lowest Gamow energy to date for studying 3He + 3He fusion in high energy density plasma.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
